JEDiagnostics is a debugging mbean for a non replicated JE Environment.
This is intended as a locus of field support functionality. While it may be
used by the application developer, the primary use case is for a support
situation. Currently much of this functionality is also available through
the standard java.util.logging MBean.

It is a concrete MBean created by registering a JE Environment as an MBean
through setting the JEDiagnostics system property. It only works on an
active JE Environment, and one Environment can only have one JEDiagnostics
instance. There are two attributes and one operation:

Attributes:

consoleHandlerLevel: which sets the console handler level.

fileHandlerLevel: which sets the file handler level.

Operations:

resetLoggingLevel: which sets the level for the current loggers in
the LogManager.

We can use these attributes and operations to dynamically change the
logging level for debugging purposes.
